I found this surprisingly well-written manual for I2C serial communication protocol today. In short, this is a fairly popular message-based protocol that can be found in many embedded systems in consumer electronics, test and automation and automotive fields. There are low-speed alternatives and the structure of the protocol is fairly user-friendly making it a good option for hobbyists. There also schematics available on-line for rs232 and USB to I2C adapters available on-line like this open-source platform.
